To all whom it may concern:

Be it known that I, SAMUEL L. KISTLER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Nozzle for Vaginal Syringes,of which the following is a specification.

This invention relates to vaginal syringes and particularly the nozzlesthereof, and the main object of the invention is to prevent the liquidwhich is injected into the vagina from escaping from the vagina whilethe syringe is in use thus rendering the douche more effective and lessunpleasant by obviating the awkward and disagreeable slopping orsplashing out of the liquid from the vagina, thus enabling the douche tobe performed neatly and with cleanliness.

A further object is to permit the liquid to be applied against the wallsof the vagina under a pressure (greater than the mere contact of theliquid) which causes the full surface of the membraneous lining toreceive actual contact of the medicinal or cleansing liquid and topermit the liquid to be washed back and forth when a bulb is usedthereby not only greatly promoting the medicinal or cleansing action,but also conserving the liquid.

The accompanying drawing illustrates the invention, and referringthereto;

Figure 1 is a side elevation of the device, the wall of the vagina beingindicated in line; the tube connection to the fountain or bulb of thesyringe being shown by dotted lines. Fig. 2 is a vertical, longitudinalsection taken diametrically through the nozzle, only the nearest portionof the inflating tube being shown, the rest being broken away. Fig. 3 isa cross section on line X X of Fig. 2. Fig. 4 is a perspective View, indetail, of the expansible dam.

The nozzle comprises a cylindrical body 1, having a front concave-convexshield 2, with a bulbous projection 3. The inner end of the body 1 has arounded extension or tip 4. A canal 5 extends completely through thenozzle. The rounded tip 4 is formed with a series of radial slots 6which communicate with the canal.

An expansible dam is arranged at an intermediate point of the nozzle andin the present embodiment comprises an inflatable tubular ring 7 formedpreferably of soft rubber, which is seated in a concave annular groove 8formed in the body portion 1. A hole 9 is formed in the body 1eccentrically of the canal 5 and communicates with the groove 8, andextending therethrough is an inflating tube 10 formed preferably of softrubber, the inner end of which joins the inflatable ring 7. The outerend of the tube 10 connects with inflating means of any desiredconstruction, for example, bulb 11. A clamp 12 is provided on tube 10 toenable the tube 10 to be closed when the ring is inflated and thusprevent the ring 7 from collapsing.

A tube 13 is attached to the projection 3 and conveys the liquid douchefrom the fountain or bulb, not shown, to the canal 5. The tube 13 is notrequired when a bulb is used as the bulb may be attached directly to theprojection 3.

14 designates the wall of the vagina.

In operation the tubular ring 7 being deflated, the nozzle is insertedin the vagina as indicated in Fig. 1, the shield 2 preventing the nozzlefrom being pushed in too far. The tubular ring 7 is then inflated bymanipulating the bulb 11 and thus forcing fluid such as water or airthrough tube 10 into the ring 7, which causes the outer wall of the ring7 to be pressed into intimate contact with the wall of the vagina asshown, and with the clamp 12 closed to prevent deflation of the ring 7the latter forms a dam which perfectly conforms to and fits the wall ofthe vagina and seals the space within the vagina around the nozzle. Thedouche liquid is then allowed to flow through tube 13 and canal 5 intothe vagina through the inner end of the canal 5 and also through slots6, and the ring 7 prevents the liquid from escaping. If desired theliquid may, by using a bulb, be caused to surge back and forth to washthe membranes. The ring 7 will withstand the liquid being introducedunder a considerable pressure and thus, aside from the advantages ofneatness, the expansible dam renders possible modes of treatment orapplication of the douche which could hitherto not be employed.

In removing the nozzle the ring 7 should first be deflated which isaccomplished by loosening clamp 12.

What I claim is:

l. A syringe nozzle comprising a body portion the tip of which has aseries of long radial slots, the body portion having a canal extendingcompletely through it with which canal the slots communicate, the bodyportion having an external annular groove, and an inflatable tubularring in the groove.

2. A syringe nozzle comprising abody portion consisting of a singlepiece of material the tip of which has a series of radial slots, thebody portion having a canal of even diameter throughout extendingcompletely through it with which the slots communicate, the body portionhaving an external annular groove, an inflatable tubular ring in thegroove, a tube extending from the outer end of the body portion to thetubular ring, and means for forcing fluid through the tube to the ringto inflate the same.

'3, A syringe nozzle comprising a body portion the tip of which has aseries of radial slots, the body portion having a canal extendingthrough it with which canal the slots communicate, the body portionhaving an external annular groove, an inflatable annular ring in thegroove, a tube extending from the outer end of the body portion to thetubular ring, means for forcing fluid through the tube to the ring toinflate the same, a shield on the outer end of the body portion, andmeans on the shield for the attachment of a syringe tube or bulb incommunication with the canal.

4. A syringe nozzle comprising a body portion the tip of which has aseries of radial slots, the body portion having a canal extendingthrough it with which canal the slots communicate, the body portionhaving an ex ternal annular groove, an inflatable annular ring in thegroove, a tube extending from the outer end of the body portion to thetubular ring, means for forcing fluid through the tube to the ring toinflate the same, a shield on the outer end of the body portion, meanson the shield for the attachment of a syringe bulb or fountain syringetube in communication with the canal, and a clamp on said first tube forclosing the tube to prevent deflation of the ring. i In testimonywhereof, I have hereunto set my hand at Los Angeles California this 9thday of November 1906.
